You can use pressure-treated wood for a horizontal fence, but you’ll need to purchase a thicker and higher-quality variety to ensure it doesn’t sag or warp after you install it. Use #2 pine grade lumber and boards and thicker dimensional lumber, such as a two-by-six. You’ll also need to use stainless steel or hot-dipped galvanized fasteners, as the chemicals in the treated lumber will cause regular galvanized fasteners to rust. 

Privacy fences in residential neighborhoods tend to stand between 6 and 8 feet tall, but local building code usually dictates the maximum height. Livestock fences that border large land plots range from 3 to 6 feet. Shorter, decorative fences, which are common in front yards, are around 3 feet tall, on average. Fence height also tends to vary by material, with wood fences usually sitting at 6 feet tall, and chain-link and wrought iron fences tending to sit at half that.

Planting greenery on a fence can help achieve more privacy, whether it’s shrubs along a picket or chain link fence or rolls of faux greenery to help create a solid-colored backdrop beyond the fence line. You can also try adding more lattice or paneling across a fence so that there are fewer places where passing eyeballs can see in.

The cost to pressure wash a house ranges from $200 to $400 and unfortunately does not include fencing. That service will be an additional charge of between $150 and $350, depending on the size of your fence and the type of material it’s made of. This also applies for other services like pressure washing a patio or deck.
